To further the goal of optimized material design for pulsed power components, we aim to achieve a fundamental understanding of the model nonlinear dielectric material BaTiO3, through concurrent experimental and theoretical study. This effort is intended to lead to improved synthesis and design control, and a validated model to enable material predictions. The ultimate goal is to improve energy...
For several years the University of Missouri has been developing compact capacitors for use in high voltage pulsed power/directed energy applications. The dielectric employed in this development is a proprietary nanocomposite, nanodielectric material, MU100. The material was originally developed for use in dielectric loaded antennas, however, due to various material properties, the...
Surface trap parameter and distribution can significantly affect the development of the secondary electron emission avalanche (SEEA), the most widely accepted mechanism for flashover in vacuum. To further understand the influence of traps on the flashover of polymeric materials under different degrees of aging, polytetrafluoroethylene (PTFE), polymethylmethacrylate (PMMA) and polyamide (PA6)...
HTV insulators are widely used in electric power system for their excellent anti-pollution flashover performance. HTV material will gradually age due to ultravilot radiation, oxidation, corrosion of acid and alkali, corona, and so on. In this paper we use laser induced breakdown spectroscopy (LIBS) to study the difference between aging HTV used in transmission lines and artificial corona aging...
